How to set up a TFTP server in Ubuntu
By Tech Junkie
TFTP (Trivial File Transfer Protocol) is a stripped down file transfer protocol. Unlike the commonly used FTP it does not contain authentication and is not suitable for use over the public internet. It is mainly used for serving boot files to embedded devices.
Install tftpd-hpa and supporting packages.
sudo apt-get install xinetd tftpd-hpa tftp-hpa
Make the tftp storage directory writeable by 'normal' users
sudo chmod -R 777 /var/lib/tftpboot
Create /etc/xinetd.d/tftp and add the following contents:
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /var/lib/tftpboot
disable = no
}Start tftp daemon through xinetd
sudo /etc/init.d/xinetd start
Now test that your tftp server is working by getting a file from your own ip address.
user@ubuntu:~$ echo "This is a test file for tftp." >> /var/lib/tftpboot/testfile.txt user@ubuntu:~$ tftp <YOUR IP HERE> tftp> get testfile.txt tftp> quit user@ubuntu:~$ cat testfile.txt This is a test file for tftp.
